** Updated: "Me and Orson Welles" has been added to this weekend's film slate. See details below **

Not counting mug shots, it's been a while since Mel Gibson has appeared in anything major -- since 2002's "Signs," to be exact.

This week, audiences will get to see if the "Lethal Weapon" star still has it in him to play a cop on the brink, as "Edge of Darkness" lands in theaters. In it, he plays a vengeance-minded police officer whose investigation into the death of his daughter uncovers some uncomfortable truths.

It leads a somewhat lackluster week at the box office, with only one other major release slated to hit New Orleans-area theaters (plus one indie documentary, and the local arrival -- finally -- of Richard Linklater's "Me and Orson Welles").

Here's the full rundown on all movies set to open Friday (Jan. 29), with details on each, as well as links to official sites and trailers where available:

Mel Gibson is a Boston homicide detective whose activist daughter is gunned down right in front of him. When he launches his own investigation into who killed her, he uncovers some troubling truths that point him back to some very powerful people.

A romantic comedy starring Kristen Bell as a woman who is chronically unlucky in love. While visiting a fabled "lover's fountain" in Rome, however, she makes the ill-advised decision to snatch a handful of coins -- which gives her more suitors than she knows what to do with.
